ADJUSTABLE EDGE-FLANGE.

Specification of Letters Patent.

Application filed December 22, 1915, Serial-1N0. 68,258: Renewed July26, 1919. Serial No. 313,479.

To all whom it may concern:

Be it known that I, MICHAEL J. MoHALE, a citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented certain new and useful Improvements inAdjustable Root Flanges, of which the following is a spec'ific.'tion.

My invention relates to new and useful improvements in an adjustableroof flange.

The primary object of the invention is the provision of a device of thischaracter which may be adjusted to accommodate itself to pipes passingthrough the roof at various angles.

A further object of the invention is the provision of means forreversing the flange whereby a greater or less adjustment may besecured.

A still further object of the invention is the construction of thedevice in such a manner as to receive and securely hold a cal king withthese and other objects in view the invention consists in the noveldetails of construction and arrangement of parts which will be moreclearly understood from the following description and drawings, inwhich,

Figure 1 is. a longitudinal section through the roof and flange,

Fig. 2 is a longitudinal section through the roof showing asideelevation of the flange, and

Fig. 3 is an end view of the flange.

In the drawing the numeral 1 indicates a roof having an opening 2therein through which a vent pipe 3 or other similar pipe may pass.

My adjustable roof flange is formed in two separate sections, onesection forming the base adapted to be secured to the roof and. theother section being connected to the base and adjustable in relationthereto. The base and adjustable section are each struck from a singlepiece of material, in the pre ferred form of my invention, but it willbe understood that the parts may be cast or otherwise constructed as maybe desired.

In Fig. 1 of the drawing, I have illustrated my roof flange as appliedto a flat roof in such a manner as to accommodate a pipe leadingstraight up through the roof and in dotted lines have shown the positionin which the device may be adjusted.

The base comprises a flange portion indishown in dotted lines.

are secured to each side of the portion 5 and form pivot points for theadjustable section to be later described. By providing the openingin theportion 5 at an angle, it will be seen that one side or end of the baseportion will be considerably higher than the other, and the purpose ofwhich will be presently described.

The adjustable portion of my flange comprises av concavo-convex memberso shaped asto fit the portion 5 of the base as is clearly shown in thedrawing. The lower edge of this concavo-convex adjustable member is cutat an angle thereby forming one end thereof, as indicated at S, of lesslength than the opposite end indicated at 9. The upper end of theadjustable concavo-convcx member is flanged as indicated at 10 toreceive a calking ring of lead or other suitopenings adapted to engagethe rivets or.

lugs 7 formed on the base portion.

Having described the detailed construction of my device, it is thoughtthat the operation and many advantages will be clearly understood. InFig. 1 of the drawings as well as in Fig. 2, I have illustrated theflange as applied to a roof and greater or less adjustment can besecured by reversing the concavo-convex adjustable member upon the base.In Fig. 1 of the drawings I have shown the adjustable member in oneposition, and in Fig. 2 I have shown it reversed. lVhen in the positionshown in Fig. 1 of the drawings, the adjustable member may be adjustedto the position illustrated in dotted lines and when in the positionshown in Fig. 2, may be adjusted to the position in full lines or raisedto the position It will be seen that when the adjustable member isreversed as illustrated in Fig. 2 of the drawings, a greater angle canbe secured than when in the position shown in Fig. 1 of the drawings. Itwill be seen that when in the position shown in Fig. 2 of the drawings,the shorter end 8 of the adjustable member allows of a greater anglebeing secured. WVhen in raised position the end of the adjustable memberwill engage the lug or projection 6 formed on the portion 5 of the base.My adjustable roof flange is particularly adapted for earrying ventpipes through roofs which may be of a greater or less angle. It will beunderstood that the pipe will pass through the opening 2 formed in theroof and then through the opening formed in the portion 5 of the base aswell as the opening formed in the adjustable member. After the pipe hasbeen passed through the adjustable member, and calking rings 11 aresecured to the flanged portion 10 on the adjustable member, the calkingelement or ring ll is then calked in and around the pipe. When it isdesired to reverse the adjustable memher to secure a greater angle, itis only necessary to engage the flared ends of the lugs or projections 7and they may be disengaged from the rivets or lugs 12.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent is:

1. An adjustable roof flange comprising a base, a cover movable of saidbase, and resilient means for removablysecuring said cover in position.

2. An adjustable roof flange comprising a base, a. concave-convex shapedcover movable of said base, and resilient means for removably securingsaid cover in position.

3. An adjustable roof flange comprising a base, a reversible covermovable of said base, and resilient means for removably securing saidcover in either of its positions of operation.

4. An adjustable roof flange comprising a base, a reversible covermovable of said base, said cover having its wall concavoconvex in formand provided with an opening disposed at one side of the center thereof,and resilient means for removably securing said cover in either of itspositions of operation.

5. An adjustable roof flange comprisin a base, a reversible covermovable of sai base, said base having its wall concavoconvex in formandprovided with an opening disposed at one side of the center thereof,oppositely disposed lugs carried by said base, and resilient ears formedwith said cover and adapted to be snapped nto engagement with said lugsfor pivotally retaining said cover in either of its operative positions.

6. An adjustable roof flange comprising a base, a reversible covermovable of said base, said cover having its wall ooncavoconvex in formand provided with a flanged opening disposed at one side of thecenterthereof, a gasket carried by the flanged wall of said opening,oppositely disposed lugs carried by said base, and resilient ears formedwith said cover and adapted to be snapped into engagement with said lugsfor pivotally retaining said cover in either of its operative positions.

7. An adjustable roof flange comprising a base, a reversible covermovable of said base, said cover having its wall concavo-convex in formandprovided with an opening at one side of the center thereof, a flangesurrounding said opening, a gasket carried by said flange and having itsinner wall flush with the exposed portion of the inner wall of saidflange, oppositely disposed lugs carried by said base, and resilientears formed with said cover and adapted to be snapped into engagementwith said lugs for pivotally retaining said cover in either of itsoperative positions.

In testimony whereof I affix my signature in presence of two witnesses.
